Patients of COPD show marked improvement with the use of Lung Flute


Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a disease of the lungs characterized by hyper-secretion of mucus. The disease is often seen in chronic smokers and is the third leading cause of death in the U.S. A new hand-held respiratory device called as the Lung Flute, which produces a low frequency acoustic wave and allows the patient to clear the mucus in his lungs by simply blowing into it, has been found to be of great help in patients suffering from COPD.

In a new research published in the journal Clinical and Translational Medicine and carried out by Dr. Sanjay Sethi from the division of pulmonary, critical care and sleep medicine in the Department of Medicine, UB School of Medicine and Biomedical Sciences, the researchers followed 69 patients suffering from COPD for 6 months. It was seen that the Lung Flute decreased the intensity of COPD in these patients and improved their quality of life.

The participants of the study were asked to fill up the Chronic COPD Questionnaire which assesses the changes observed in the symptoms of COPD. They were also asked to fill up the St. George’s Respiratory Questionnaire which measures the changes seen in the quality of life of the patient. The patients using the Lung Flute during the study period reported significant improvement in both the questionnaires.

Along with the questionnaires, the BODE score of the patients was also measured repeatedly. BODE stands for the body-mass index, airflow obstruction, dyspnea observed and the exercise capacity. The BODE score gives a fair assessment of the COPD symptoms in a patient. As the disease worsens, the BODE score goes up. During the study, the patients using the Lung Flute had a flat BODE score whereas the BODE score of the control group increased.

The Lung Flute has been approved by the FDA for the treatment of COPD and other diseases of the lungs characterized by excessive mucus secretion. It has also got the approval of the FDA for the collection of deep lung sputum for diagnostic purpose. Dr. Sethi along with his colleagues is now studying the role of Lung Flute in improving the symptoms of asthma.
